RAILWAY TIME-SIGNAL.

JEECIFICATION forming part of Letters Patent No. 451,193, dated April28, 1891.

Application filed February 9, 1891. Serial No. 380,809. (No model.) I

To all whom it may concern.-

1 3e it known that I, OSCAR V. BLAZIER, a citizen of the United States,residing at Gillette, in the county of Morris and State of New Myinvention relates to the peculiarities of construction and combinationsof devices, hereinafter set forth, whereby the sudden movement resultingfrom the passing train does not injure any of the parts and theyare verymuch more simple and cheaper than those heretofore employed for thispurpose.

In the drawings,Figure 1 is adiagrammatic View of my signaling device,and Fig. 2 is a danger.

plan representing the track-lever.

One rail of the track is represented at H,

and adjacent to the same is a track-bar A with inclined ends over whichthe wheels of the locomotive or car pass and depress this track-bar, andthere is a lever A pivoted at- 2 and connected with the track-bar A, andthis lever i extends to the inclosure or support for the signalingapparatus, and there is upon this lever A? a weight B, sufficient forthe purpose of moving the signal apparatus hereinafter described.

The semaphore or visual signalO is pivoted at 3 upon the signal-post orinclosure, and there is a link at connecting the inner end of thissignal with the lever A, and the weight Bis sufiicient to raise thissignal 0 to its normal position of safety, and when the train in passingdepresses the track-bar A the weight B is raised by a direct action andthe semaphore. G falls by its own weight to a horizontal or nearlyhorizontal position to indicate It will now be understood that if theseparts only were made use of the semaphore would move up and down as thewheels of the railway-train passed along over the track-bar A, and whenthe train had entirely passed by the semaphore would be raisedimmediately to a position indicating safety. To prevent this operationand to insure a gradual movement of the semaphore 0 upon its return froma position of danger to that of safety, I employ a train of gearing D,with a rapidly-revolving fly E and a motor-barrel K, over which a strapI passes from the lever A to the weight L. Hence when the lever A israised suddenly the strap I is relieved of strain and the slack thereofis taken up by the weight L, such strap 1 sliding freelyover themotor-barrel K by the action of the counter-weight L, because such strap1 is entirely slack; but as soon as the weight B commences to descendthe strap is tightened, the weight L being at one end and the weight Bat the other. This weight B, however, is sufficient to overcome theweight L and cause the rotation of the motor-barrel K, train of gearingD, and the fly E, and the weight B can only descend slowly according tothe speed of rotation of the train of gearing and there is nothing thatis liable to get out of order, and the belt or band I, being usually ofleather, is very durable and it is inexpensive to replace the same whenworn out, and there are no ratchets and pawls that are liable to beinjured or to fail in operation.

These signals are to be placed at suitable distances along the track,and they indicate approximately the time that has elapsed from thepassing of the train by the position of the semaphore upon its upwardreturn movement, so that one train may be kept at the properdistancefrom another train and accidents prevented.

I claim as my invent-ion- 1. The combination, with'the track-bar A,lever A, and weight 13', of a visual signal, a direct connection betweenthe lever and visual signal for displaying such signal when the weightof the lever is raised by the passing train, a fly and train of gearingand a motor-barrel upon such train of gearing, a strap connected withthe weighted lever and passing over the motor-barrel, and acounterweight to take up the slack of such strap,

whereby the fly and gearing regulate the time barrel, a counter-weightto take up the slack consumed in the parts returning to their norof suchstrap or band, and a regulating-fly mul position by the weighted lever,substnnand train of gearing for driving the same from tially as setforth. the motor-barrel, substantially as set forth.
